Hi everyone,
a colleague has restored a backup from an older version of Postgres
(unknown) to version 10. Everything appears to be working fine with the
exception of the text search.
If I try:
select to_tsquery('english', 'hello');
I get the error
ERROR: invalid input syntax for type oid: "english"
LINE 1: select to_tsquery('english','Hello');
I can see from \dF that I have 'pg_catalog.english' installed. It works
if I do not specify the dictionary using:
select to_tsquery('hello');
Any ideas how to fix this? I have read in older support forums that the
problem may be related to older contrib methods for ts_query. If this is
so - how do I remove the contrib decalrations?
Thanks
Howard
